There are exactly three non-trivial solid varieties of semirings, the variety of all rectangular semirings, the variety V NID of all normal, idempotent, distributive semirings, and the subvariety of V NID which is defined by the additional identity x + y y + x โ‰ˆ xy + yx. ๏ฃฉ 2002 Elsevier Science (USA

We prove a structure theorem for conic involutive varieties of the cotangent bundle of a smooth algebraic variety X whose projection on X is smooth. The paper includes an example of a conic involutive variety of T เฌ™ X which is not the characteristic variety of any D D -module.
